Darpa developing tasty food from air, water, electricity.

DARPA’s Cornucopia program aims to create a variety of healthy new microbial-based foods using three ingredients — air, water, and electricity—with minimal or no supplementation. If successful, troops one day could deploy with a transportable system that makes nourishing and appetizing food on demand in remote locations, obviating costly and brittle food supply chains.

Three teams are now on contract to demonstrate production of microbial biomass consisting of all four human dietary macronutrients — protein, carbohydrate, fat, and dietary fiber — in ratios that target Military Dietary Reference Intake (MDRI) daily requirements for complete nutrition. Outputs will be in multiple food formats such as shake, bar, gel, and jerky that meet military nutritional standards and palatability requirements in a production system minimizing inputs, handling, and footprint.
